Hi I have tried the below code and dont know where I have to pass this with value because the value is filled by the user.

What I have tried:

C#

private static int CalculateAge(DateTime DOB)
{
    int age = 0;
    age = DateTime.Now.Year - DOB.Year;

    if (DateTime.Now.DayOfYear < DOB.DayOfYear)
      age = age - 1;

    return age;
}

protected void Calendar1_SelectionChanged1(object sender, EventArgs e)
{
    txtbox2.Text = Calendar1.SelectedDate.ToString();
    //int CalculateAge()

    Calendar1.Visible = false;
    txtAge.Text= CalculateAge()
}

What is stopping you from passing the value to the method?

Solution 1

I'm not quite sure, if your

Calendar1.SelectedDate

is already a DateTime.

If so, you should pass this as argument into your function. If not, you have to parse the value to DateTime and then pass it.

what i understand that you are not sure what is the event, you should handle to reflect the age immediately after typing the age not after lost focus. if this is a desktop application, there should have been some on change event or keypress event. But you must check the date is valid before calculating the Age.

Hope this would help you.

Solution 3

Use DateTime.Parse or DateTime.ParseExact to convert your Calendar1.SelectedDate.ToString() to a DateTime object and just pass this object to the CalculateAge(..) method. That's all.

Sample:
Use it inside Calendar1_SelectionChanged1(...),

C#

DateTime txtMyDate = 
  DateTime.ParseExact(txtbox2.Text, "M/d/yyyy", CultureInfo.InvariantCulture);

Also can use DateTime.TryParseExact.

Hi
I have tried in this way but the result is showing me to conversion failure int to string

My Code
protected void Calendar1_SelectionChanged1(object sender, EventArgs e)
{
txtDob.Text = Calendar1.SelectedDate.ToString();
Calendar1.Visible = false;
int year = DateTime.Now.Year - Calendar1.SelectedDate.Year;
int months = DateTime.Now.Month - Calendar1.SelectedDate.Month;

string ageval = ((year - 1) + " years" + (-12 - months) + " months");

if (months > 12)
{
year = year + 1;
}
int value = int.Parse(ageval);
value = (ToString(txtAge.Text)) ;
